Description
Technical field
The utility model is to produce Explosive Composite Material with explosion welding method, belongs to composite material manufacture neck
Domain.
Background technology
Metallic composite be one kind using stainless steel, carbon steel or low-alloy steel as substrate, single side or multi-panel are with valuable gold
Belong to the bimetallic high efficiency energy saving new composite material for cladding, can mainly reduce equipment manufacturing costs, and your dilute gold reduced
The consumption of category.Metallic composite has been widely used for oil, chemical industry, shipbuilding, electronics, electric power, metallurgy, machinery, aviation boat
It, the industrial circles such as atomic energy.A little corrosion resistance, the wearability with precious metal of metallic composite, and there is carbon
The good solderability of steel, mouldability, extensibility, thermal conductivity；It is all to Explosive Composite Material demand and day in equipment at present
Increase, explosive composite material has strong corrosion resistance and very high economy.
The usage amount of titanium/steel composite board at present, it is all increasing every year, especially in some particular surroundings, titanium/steel for using
Composite plate, area is larger, and intensity requirement is high.The cladding produced at home is the titanium/steel composite board size of 8mm or more in 2500*
Within 4500, it is primarily due to that cladding is thicker, the explosive charge of unit area increases, high temperature, the height generated during explosive detonation
Pressure causes the detonator region compound layer titanium/steel composite board interface of detonation to generate frangible compounds, as area increases big, brittleness
It closes object and forms accumulation, cause locally to generate between two kinds of metals unbonded, can not reprocess.
The double-deck titanium plate/steel plate composite plate subsequent explosion welding method can obtain high performance titanium/steel composite board.
Utility model content
The utility model aim is to propose a kind of double-deck titanium plate/steel plate composite plate, using explosive as the energy, by secondary
The compound method of explosive welding produces titanium/steel plate composite plate, improves the qualification rate of product, economizes on resources, meets China's chemistry work
The needs of industry development.
The technical solution of the utility model is：The double-deck titanium plate/steel plate explosive clad plate, it is characterized in that including explosion weldering successively
First layer titanium plate and steel plate, the second layer titanium plate connect, the detonator region of the detonation of first layer titanium plate/steel plate explosive clad plate is by machine
Tool removal, second layer titanium plate Explosion composite is on first layer titanium plate/steel plate explosive clad plate；The double-deck titanium plate/steel plate explosion is multiple
The thickness of every layer of titanium plate is in 2-3mm in plywood, the double-deck titanium plate/steel plate explosive clad plate of the thickness of steel plate in 5cm or more.
The preparation method of the utility model：Conventional method is pacified between cladding titanium plate and Substrate sheet using support pad
Dress lays explosive in cladding titanium, and detonation region arranges high explosion velocity ignition charge, is finally allowed to realize the continuous welding of large area,
After Explosion composite, after thermally treated, smoothing, the detonator region cladding of detonation is mechanically removed, then carry out second
Secondary explosive welding.It is installed using support pad between cladding titanium and the titanium/steel composite board that explosion obtains for the first time, is multiple at second
Layer titanium lays explosive, obtains a kind of a kind of composite material of titanium/titanium/steel (plate), after thermally treated, smoothing, mechanically
The detonator region cladding of second of detonation of removal, takes manual argon arc welding heap to be welded to base material and flushes.Meet NB/T47002.3-
2009《Pressure vessel Explosive Welding Composite Plates Part III titanium-steel composite board》The requirement of standard, by being pasted after Explosion composite
Conjunction rate reaches 99% or more, minimum shear strength τb≥140Mpa。
The Explosion composite of titanium/steel explosive clad plate is using titanium plate as the cladding of contact corrosion medium, and steel plate is used as and bears
The base of load.Compound plate is accelerated to substrate successively under the action of explosive energy during Explosion composite, and is formed certain
Bending angle, effective combination between base, compound plate could be formed.Due to difference between two kinds of metallicities, in Explosion composite process
Middle formation bending angle is more difficult, therefore static parameter must use small―gap suture, small pit goaf.It can avoid the accumulation of both ends jet stream and combine
Face generates frangible compounds.
The utility model meets NB/T47002.3-2009 for titanium/steel Explosion composite fitting rate and shear strength《Pressure
Container Explosive Welding Composite Plates Part III titanium-steel composite board》The requirement of standard meets the industry developments such as domestic chemical industry
It needs.
Description of the drawings
FIG. 1 is a schematic structural view of the utility model.
In figure, in 1 explosive clad plate of first layer titanium plate 2-1/ steel, the detonator region 2-3 of first layer titanium plate detonation is mechanical
Removal, second layer titanium plate 2-2 Explosion composites are on first layer titanium plate/steel explosive clad plate；The thunder of second layer titanium plate 2-2 detonations
Area under control domain 2-4 should also be removed.The thickness of every layer of titanium plate exists in 2-3mm, the thickness of steel in the double-deck titanium plate/steel explosive clad plate
The double-deck titanium plate/steel explosive clad plate of 5cm or more.
Specific implementation mode
The embodiment of the utility model is specifically described below.
The Explosion composite of titanium/steel explosive clad plate is to be placed on titanium plate above when installing at the scene, and steel plate is as following
One laminar substrate, supporting gap uses 8mm between two plates first, to meet the needs of low-angle installation, and in order to avoid dose is big
Can burn compound plate face during Explosion composite, and protective layer will also add protective layer.Main body explosive selects powdery emulsifying explosive, explosion velocity
≥3200mm/s.Titanium plate surface is evenly arranged powdery emulsifying explosive after being protected, and high explosion velocity ignition charge is arranged in detonator zone,
2500 ± 50mm/s of its explosion velocity, fire point are placed on compound plate.After Explosion composite, thermally treated, leveling, fire point processing, by upper
It states method and carries out second of explosive welding, thermally treated, leveling, fire point processing obtains titanium/steel composite board, detonates twice
Position differs, and carries out argon arc welding repair welding reconditioning；Carried out during second of Explosion composite, between titanium and titanium it is compound, will not
Frangible compounds are generated, and interface bond strength can be very high.Our company produces material：TA1/Q345R, size：8/45*
The explosive clad plate of 2500*7500, by NB/T47002.3-2009《Pressure vessel Explosive Welding Composite Plates Part III titanium-
Steel composite board standard is detected fitting rate and shear strength, and fitting rate is 100%, shear strength τb≥140Mpa.Second
The detonator region 2-4 of layer titanium plate Explosion composite detonation should also be removed.
The utility model provides high-performance titanium/steel composite board, and not only fitting rate is high, but also shear strength is high, solves
Large area titanium/steel composite board fire point is not bonded, and reduces risk of material during explosive forming.The utility model
The advantages of having taken into account two kinds of base, cladding materials, not only makes two kinds of materials firmly be combined together, and ensures that long-time service will not
Layering, and reduce the consumption of rare precious metal.
